Hmm, was ready to give this one a miss (especially since this is the first I've even heard of it) but then you mentioned Tarsem Singh. I've only seen two movies by him, Immortals and The Fall. The first of those was...alright I guess. I think I have a soft spot for it because I love Greek myth and saw it on a date. But The Fall I absolutely love because holy shit its gorgeous. And actually has a decent and actually kind of complex story to it. Seriously, go watch it, you need to see it at least once.
By the sounds of it this is just a generic shoot 'em up though and has none of Tarsem's signature batshit crazy visuals, which kind of makes me wonder what the point of getting him to do it was...
